Abstract

PCT No. PCT/EP91/02202 Sec. 371 Date Jun. 1, 1993 Sec. 102(e) Date Jun. 1, 1993 PCT Filed Nov. 22, 1991 PCT Pub. No. WO92/09526 PCT Pub. Date Jun. 11, 1992.The invention is a process for the hydrothermal production of crystalline sodium disilicate by heating an aqueous mixture of quartz sand and sodium hydroxide or an aqueous solution of sodium disilicate with a solids content of at least 50% by weight or more than 75% by weight at a temperature above 235 DEG C. and under autogenous pressure to form crystalline sodium disilicate.
